Nan Zhiqiao continued to look through the information.

Fourth household: Tashi's brother-in-law, only one member of the family lives alone, and he has not died of illness.

Tashi's brother-in-law had taken care of Tashi before his illness and had been resting at home since his illness, with no contact with anyone else.

Fifth household: Dawa's family, 7 people in the family, 4 people died, 1 person died.

The four patients in the household are Dawa and Dawa's father, younger sister and eldest sister.

Dawa, female, 37 years old, herder, Tibetan, became ill on April 20 and died on April 23, that is, yesterday, before the onset of the disease, took care of Tashi's third son, who was sick.

Dawa's father, younger sister and eldest sister also fell ill and are currently being treated in isolation at home, all of whom had been in contact with Tashi's sick third son before the onset of the disease.

After reading all the case flow data, Nan Zhiqiao continued the question just now, "Except for Tenzin, who was buried in the sky, the other six deaths were all burials, did they collect corpse specimens?"

"Not yet. "After repeated discussions, our investigation team decided to collect the remaining bones of the corpses that have been buried in the sky for testing, and for the corpses that have been buried, they will be re-exhumed for acute autopsy and sampling testing." ”

"It was the right decision. Nan Zhiqiao agreed.

Dorjee looked embarrassed, "In the process of consultation with the patient's family, although there was a policy requiring an autopsy, we still encountered strong opposition from the family of the deceased patient, and the investigation was delayed. ”

Nan Zhiqiao understands the difficulties of the investigation team, and it is difficult for the family to accept the fact that it is against local customs to dig up the buried people again, without a strong and legitimate reason.

The first thing to solve now is to find such a reason, a reason to get the families to agree to the exhumation of the body and the sampling.

Zhen Zhen saw a corner of the temporary tent, where a lot of protective and sampling equipment was piled up.

Zhen Zhen asked Dorjee, "Have you taken samples from people who have been in contact with the deceased?"

"I took it and sent it to the state CDC this morning, and the test results will be fed back tomorrow. ”

Zhen Zhen thought of an idea and suggested: "We came this time, and we brought a lot of colloidal gold kits that can quickly detect Y. pestis on site, and the results can be obtained in 20 minutes, and if we can detect Yersinia pestis from the environment in which the deceased lived before his death, or from the people who came into contact with him, then this is the best reason to persuade the family of the deceased to agree to exhum the body and take samples." ”

Dorjee and Lao Zhao both agreed with Zhen Zhen's suggestion, and finally, Nan Zhiqiao nodded, "Okay, let's go take samples now." ”

——

It was already late in the evening after the meeting within the investigation team.

Wearing protective clothing, bringing the sampling box, the investigation team prepared to go to the small isolation circle to take samples under the slanting sunset.

It takes more than 10 minutes to walk from the makeshift medical tent to the nearest villager's tent.

Wearing a protective suit and carrying a sampling box, Zhen Zhen felt a little depressed, Zhen Zhen thought to herself, she usually wears a protective suit and does not feel so stuffy, could it be because of the long journey this time?

The first place the investigation team went to was the house of Tenzin, the village doctor.

Tenzin died, and the whole family was still immersed in grief.

Dorjee had done an on-site investigation of the disease before, dealt with the villagers, and came to the door again to explain the intention, not to dig up the grave, but to sample the environment and family members, and the villagers were very cooperative.

Zhen Zhen first took samples of blood, sputum and urine from the villagers, and collected inguinal lymph node puncture fluid from domestic animals, soil, dust, surfaces of objects suspected to be contaminated by Y. pestis bacilli, and swabs from animal fur.

The investigation team divided the work, and by the time the specimens of the 37 villagers had been collected, it was already sunset, and it was completely dark.

The last villager sampled by Zhen Zhen was Dawa's family, which is the fifth family in the survey data, Dawa has died, and three of the remaining six family members have developed symptoms.

Dawa's husband, Nima, looked sad and watched the disease control personnel in full protective gear reappear in their home, and Nima's eyes were a little frightened.

After collecting Nima's blood, Zhen Zhen's eyes stayed on Nima's face.

The Tibetan man in front of him, who was almost forty years old, had a dark face, and his Tibetan clothes were stained with a few white wools, and he looked like he had just returned from the sheepfold.

Zhen Zhen felt that the Tibetan man in front of her was a little familiar, as if she had seen it somewhere, but she couldn't remember it for a while.

Look at the Tibetan man in front of him again.

Nima was a little uncomfortable when she was stared at like this, and sat aside with her eyes flashing.

The furnishings resemble those of ordinary Tibetan herders, with a stove in the middle for heating, surrounded by blankets made of yak fur and other necessities, the most conspicuous of which is a wolf skull ornament.

Zhen Zhen stared at the wolf skull, remembering that she had seen an identical wolf skull ornament in the camera of a male passenger at the airport, and a man wearing a hidden suit was taking a photo with the wolf skull, and that man looked like Nima in front of her.

Nima pointed to the wolf's skull and said, "I hunted this wolf when I was twelve. ”

Nyima spoke Tibetan, and Dorjee was on hand to help translate.

Zhen Zhen asked, "Some time ago, did a photographer take a photo of you and the wolf's head?"

"Photographer?" Nima struggled to recall, "Ten days ago, an out-of-t-town came to visit us and stayed at my house for two nights, and he had a camera in his hand. ”

Zhen Zhen took out her mobile phone, which contained a photo of a male passenger at the airport, and showed the photo to Nima, who recognized it at a glance, "It's him, he is the person who lives in my house, he said that he came to Tibet to collect style, and he has been to many places before, but he still thinks we are the most magnificent here, and he also took pictures with my family, he likes this wolf head very much, I told him the story of wolf hunting when I was a child, and he took a photo of me and the wolf head." ”

Zhen Zhen's brow furrowed slightly, it seems that the plague bacillus on the male traveler was infected from here.

Seeing Zhen Zhen's heavy expression, Nima asked worriedly, "How is he? Is he infected?"

"He was infected with Yersinia pestis and had died three days earlier. ”

Speaking the truth, Zhen Zhen's intention was to use the death of the male passenger to get Nima to agree to dig up the grave and take samples of the body.

Nima's face changed drastically, and his already somewhat sad and panicked face turned into horror.

Zhen Zhen comforted in time: "The plague can be prevented and treated, as long as the cause is determined and treated in time, death can be avoided." ”

Nima's eyes lit up and she asked, "Are we sick with the plague?"

"It's uncertain at the moment, it depends on the test results, and the testing of the deceased is also important. ”

"You're trying to dig Dawa out of the grave, right?" said Nima, knowing Zhenzhen's intentions.

Zhen Zhen did not hide it, and said bluntly: "Sampling and testing the deceased is more conducive to determining the cause and controlling the epidemic." ”

Nima's face changed, and he could see that he was struggling with thoughts, and finally, Nima let go, "If the other families agree, we will agree." ”

Lao Zhao and Duoji, who sampled together, looked at Zhen Zhen and Nima in surprise, but they didn't expect that the investigation team didn't let Nima agree after spending so many words, and Zhen Zhen did it in two sentences.
